The research interests of S.A. Stern are in the areas of structure/permeability relationships of "rubbery" and "glassy" polymers; mechanisms of gas solution and transport in polymer membranes; molecular dynamics simulations of gas diffusion in polymers; membrane processes for the separation of gases, vapors, and liquids; and hybrid separation processes. His research group has pioneered in the development of membrane processes for gas separations of industrial interest.
